Ice Thickness: None
Road Conditions: Open
Trail Conditions: Wet and muddy in spots. Please tread lightly.
Due to the Bison Roundup, all backcountry trails will closed on Saturday, Oct 27, 2018. Trails on the north end of the island will remain open.
Fire Restrictions: Fires are permitted in designated fire pits within Bridger Bay and White Rock Bay Campgrounds.
Note: Water depth at the mouth of the marina is approximately 2 feet. Shallow areas and sandbars exist, use caution.
Insects: During warm months, insects are present on the island and emerge at different times.
- Biting gnats (no-seeums) emerge in the spring (April – June). These are very tiny biting flies. Insect repellent is ineffective against the gnats; fine-mesh head nets are recommended. They are not present along the water’s edge.
- Midges are non-biting flies that form columns along the causeway mid-spring through early fall. These are what cover your windshield while driving to and from the island.
- Mosquitoes are present from mid- spring through early fall. Insect repellent is effective. Note: West Nile Virus has been found in Davis County.
- Brine Flies are non-biting flies that cover the shorelines and occasionally move onto land early-summer through fall. These flies are harmless and move out of the way when approached.
